Lowers under-hood temps up to 50%, Wraps around headers, mufflers, and pipes Give your header and exhaust system a custom look with our Lava Exhaust Wrap. Made from crushed volcanic rock, our Lava Wrap has all the same benefits as exhaust wrap with that trick carbon fiber look and improved durability! This exhaust wrap is 25% stronger than fiberglass wraps, giving it a prolonged life and greater durability. Using Lava Wrap on a header and exhaust system, it maintains hotter exhaust gases, decreases gas density, and that allows the exhaust gas to flow out system faster! Greater exhaust scavenging is produced, pulling intake gases through the cycle faster, helping to lower air intake temperatures. This gives you more horsepower! This wrap also reduces radiant heat damage and can lower under hood temperatures by as much as 50%. Our Lava Wrap withstands 1200F continuous (please note this is a real world tested rating, please don't believe over inflated temperature ratings of similar basalt/volcanic rock products) and 2000F intermittent. Wrap Lava Wrap around your exhaust pipe, using overlap to hold itself in place (like a hockey stick or tennis racket grip) use our Thermal-Tie, hose clamps, or wire to secure ends in place. Lava Wrap is asbestos free and is made from a base high quality basalt yarn. It is noncombustible and it is also chemical, water, and acid. Always wear gloves, safety glasses and dust mask when handling this product, long sleeves are also recommended. Rated for 1200F continuous use, 2000F intermittent Reduces under hood temperatures up to 50 percent Increases horsepower All rolls 1/16 inch thick
